<DIV>Hi Tom,</DIV>
<DIV>I suspect that there is something attached to the felt on the =
edge of the
fallboard. or loose felt with hard glue making a noise against the =
wood.</DIV>

<DIV> </DIV>
<DIV>Here's a puzzler for you all; an unsolved puzzler at =
that. I've
executed a repair, but I have no idea why it works...</DIV>
<DIV> </DIV>
<DIV>Kawai grand, about 15 years old. There's a click on =
F#2,
G#2, and A#2 when the key is depressed. Not when it's released =
but at
the moment they're depressed quickly. (It won't happen on a =
slow
strike.)</DIV>
<DIV> </DIV>
<DIV>I take the action out to check for loose screws, debris on the =
keys,
any anomaly, but nothing. In fact, the click is gone. I =
did
tighten one screw on one of the action rails, so, maybe that was =
it...</DIV>
<DIV> </DIV>
<DIV>Put the action back in, still no click. Reinstall the =
cheek
blocks, still no click. </DIV>
<DIV> </DIV>
<DIV>When I put the fallboard back on, there's the click =
again. Pull
the fallboard forward to a 45 degree angle, no click. Back to
vertical, click,</DIV>
<DIV> </DIV>
<DIV>OK. The keys must be hitting the fallboard, but wait a
minute. It happens when the key goes down, not up. The =
fallboard
does not extend backwards inside all the way to the back side of the =
balance
rail, so when the key goes down, there is MORE clearance from the
fallboard. If the click was on the way up, I'd say it was =
hitting the
fallboard when it returned to the up position, but it happens on the =
way
DOWN!</DIV>
<DIV> </DIV>
<DIV>Am I just stupid? Am I missing something here?</DIV>
<DIV> </DIV>
<DIV>My solution? I raised the fallboard so that there =
was more
clearance from the keys and now there's no click. </DIV>
<DIV> </DIV>
<DIV>But how can the keys strike the fallboard on their way down and =
make a
noise? It doesn't make sense.</DIV>
<DIV> </DIV>
<DIV>It's not the upstop rail being depressed by the fallboard (That =
click
would happen on the way up, too.). I put felt on the backside =
of the
fallboard at the point where the keys would come into contact with =
it if
that was the problem to see if that changed the sound or eliminated =
it,, but
it didn't have any impact.</DIV>
<DIV> </DIV>
<DIV>I guess I should move on, because I fixed the
problem. But I just want to know: what caused the
click?<BR></DIV>
<DIV>Any ideas? Did I describe this well enough? </DIV>
